A common misbelief is that arm balances require tremendous shoulder strength. This misunderstanding embodies the idea of avidya, or nonseeing, a central concept in Patanjali’s Yoga Sutra. Patanjali suggests that avidya is the root cause of all suffering: When we fail to see things accurately, we are inhibited in our ability to act skillfully. The upper body does play a significant role in poses like Eka Pada Koundinyasana I, but learning how to use the legs and a very specific part of the foot—a habit you can start to form in Chaturanga—can have a transformative effect. As you practice, see what happens when you invite the lower body to become a more active participant. Where else in your life might misperception be distorting your experience?

Maintain a straight line from the knees to the crown of the head, keeping the tailbone moving toward the heels and the lower belly toned, while eliminating any flexion in the hips. As you exhale, bend at the elbows and lower as far as you can while keeping them pinned to your sides.
